Model sensitivity to prompt formatting
Category: Attacks on GPAIs/GPAI Failure Modes
Description
"LLMs can be highly sensitive to variations in prompt formatting, such as changes in separators, casing, or spacing. Even minor modifications can lead to significant shifts in model performance, potentially affecting the reliability of model evaluations and comparisons. This sensitivity persists across different model sizes and few-shot examples [177]."
